Research ArticleOpen accessIn the abstractA NOVEL ROBUST AND EFFICIENT TOOL FOR DETECTING HETEROSCEDASTICITYWei Xiong, Maozai TianOne of the greatest values of Quantile Regression (QR) is that it provides a good procedure in the sense that QR could be much more efficient and sometimes arbitrarily more efficient in recovering the mean function than the Least Squares (LS) even when without moment conditions. However, heteroscedasticity definitely causes conditional variances of parametric or nonparametric estimates of mean functions … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 21 Mar 2014 · 6,657 accessesView PDFCite

Research ArticleOpen accessIn the abstractTesting and Performance Evaluation of Tractor Mounted Hydraulic Elevator for Mango OrchardKishor P. Kolhe, Bhaskhar B. JadhavProblem statement: The harvesting and pruning of horticultural crops is quite difficult due to their tallness. There are small hand tools available for harvesting and pruning. But these tools of harvesting and pruning are restricted due tree height, unavailability of trained labours for climbing and cost of operation etc. The mechanized machines are available; these are heavy and costly and … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 26 Mar 2011 · 8,887 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Cost Effective and User Friendly Approach to Design Wireline Formation TestsClara Bertolini, Giuseppe Tripaldi, Elena Manassero et al.Problem statement: Wireline formation testing (also named Mini-DSTs) are gaining more and more popularity as a possible alternative to conventional well testing especially where there are major environmental and economical constraints. The increased offshore exploration activity, which often implies highly risky and huge operational costs, makes the conventional well testing less attractive in favor of other technologies that can provide … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 6,665 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Complete Automation of Unit Testing for JavaScript ProgramsM. AlshraidehProblem statement: Program testing is expensive and labor intensive, often consuming more than half of the total development costs, and yet it is frequently not done well and the results are not always satisfactory. The objective of this paper is to present an automatic test data generation tool that aims to completely automate unit testing of JavaScript functions. The methodology: … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,289 accessesView PDFCite
Research ArticleOpen accessIn the abstractTesting Virtual Reconfigurable Circuit Designed For A Fault Tolerant SystemP. Nirmal Kumar, S. Anandhi, M. Elancheralathan, J. Raja Paul PerinbamThis research describes about the testing of virtual reconfigurable circuit (VRC) designed and implemented for a fault tolerant system which averages the (three) sensor inputs. The circuits that are to be tested are those which are successfully evolved in this system under different situations such as (i) all the three sensors are faultless (ii) one of the input sensor fails … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 6,854 accessesView PDFCite
Research ArticleOpen accessIn the abstractData-Driven Forecasting Schemes: Evaluation and ApplicationsJosip Vrbanek Jr, Wilson WangA reliable multi-step predictor is very useful to a wide array of applications to forecast the behavior of dynamic systems. The objective of this paper is to develop a more robust data-driven predictor for time series forecasting. Based on simulation analysis, it is found that multi-step-ahead forecasting schemes based on step inputs perform better than those based on sequential inputs. … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,565 accessesView PDFCite
